Evidence Checklist: Complex Regional Pain Syndrome (CRPS/RSD)

Specialist diagnosis from pain management or neurologistCritical

A formal CRPS diagnosis from a pain management specialist or neurologist using the Budapest Criteria, documenting sensory, vasomotor, sudomotor/edema, and motor/trophic signs.

Nexus opinion linking CRPS to original in-service injuryCritical

A medical opinion connecting your CRPS to the original in-service injury, surgery, or trauma that triggered the condition. CRPS is almost always secondary to an initial injury.

Three-phase bone scan or thermographyCritical

Diagnostic imaging showing asymmetric blood flow and temperature changes characteristic of CRPS. A three-phase bone scan is the most commonly used objective test.

Treatment records showing refractory pain management

Records documenting extensive treatment attempts including nerve blocks, medications, physical therapy, spinal cord stimulators, and pain management programs, showing the condition is difficult to control.

Photographic evidence of skin, color, and temperature changes

Dated photographs showing visible signs of CRPS including skin color changes, swelling, hair/nail growth changes, and temperature differences compared to the unaffected limb.

Buddy statement from spouse, family, or fellow service member

A written statement from someone who can describe observable symptoms and how your condition affects daily life.

Completed DBQ Peripheral Nerves ConditionsCritical

Standardized form capturing nerve involvement severity, sensory and motor deficits, and trophic changes associated with CRPS.

Documentation of original in-service injuryCritical

Service treatment records showing the initial injury, fracture, surgery, or trauma that preceded the development of CRPS.

Service treatment records (STRs)Critical

Military medical records showing in-service treatment, complaints, or injuries related to this condition.
